Virtual Expert Inbound Video Support Application:

For OEM equipment vendors such as medical image devices, enabling customers to
share images with their colleagues can be a key differentiating feature of their
products and services.

In this sample application VGA Broadcaster Lite is used to provide live video to a
telemedicine expert in order to deliver better healthcare services at a distance. It is
connected to medical equipment and transmits medical data/information to a
remote expert through the Ethernet connection.

This application enables immediate consultations with the medical device’s product
specialist, or another specially skilled remote medical professional without the need
to be present with the equipment or patients

Assisting Mobility, Visual or Hearing Impaired

Attendees

VGA Broadcaster Lite allows conference organizers to provide facilities for
hearing/visual/mobility impaired. This device allows either broadcast event via
Internet for those who are not able to attend or helps visual and hearing impaired
attendees display and/or amplify the conference content on their local computers.
